Innovative Technology of Coating & Overlay for Maintenance and Repair

We would like to introduce a Japan’s Best Coating & Overlay Device already approved and installed by all of Japanese Automobile companies and NASA.

SparkDepo

The SparkDepo is a new surface enhancement process, and deposits an alloy or applies a hard coating by means of electric sparks from rotating electrode.
Preventive maintenance of various machine components, tooling, dies, and molds can be accomplished by the application of hard coatings using WC, TiC, TiB2, Cr3C2, VC, etc. electrodes. Low heat input alloy overlay is posssible using the electrod of Ni, Co, Cu, or Al alloys. The SparkDepo process is truly a new plant maintenance technique. The use of SparkDepo really increases productivity and reduces maintenance cost because of the reduced maintenance time and parts inventory.

1 Low heat input with no melting of the base metal.
2 No distortion and residual stress.
3 No change in the hardness of the base metal.
4 Controlled thickness within 0.01mm.
5 Reduction in finishing time due to reduced finishing stock.
6 No requirement for pre/post heat treatment.
7 Carbide coating
